But the thing is I was under the impression that in a ppm image the
maximum or the min color value that any of the R,G and B components
can take...i.e. if instead of 255 in the file below, if I give 16 then
automatically it would imply my color space has changed to RGB 4:4:4

extensive googling didn't help, so here I go. I produce PNG files with lot's of

When I try to open them, they are im.mode='RGB', ie all the transparency is
gone. This is the same in PIL

the same way as you'd save any PIL image:

Yeah, but
